I never meant for it to happen, but once I saw my son's hard cock, there was no going back. It was a normal Saturday night, the house quiet after my husband left for his usual weekend trip. I was in the laundry room folding clothes when I heard the shower running. Curiosity got the better of me. I pushed the door open a crack, and there he was, eighteen and built like a man now, his body slick under the water. His hand was wrapped around his thick, throbbing cock, stroking it slow and firm. It was huge, veined, the head flushed dark and leaking. My pussy clenched instantly at the sight.
I should have closed the door. Instead I stood there, watching him pump that sons hard cock with both hands, his hips thrusting forward. He groaned my name under his breath. "Mom…" That did it. I stepped inside, closed the door, and let my robe fall open.
"What the fuck are you doing, Mom?" he asked, but he didn't stop stroking. His eyes locked on my bare tits and the wet slit between my legs.
"Keep going," I told him, voice low and dirty. "Show me how you jerk that big hard cock for your mother."
He did. He stood there in the shower, water running down his chest, and stroked faster while I watched. My fingers slipped between my folds, rubbing my clit in time with his fist. "That's it, baby. Make it harder. I want to see you cum for me."
He stepped out dripping, cock bouncing heavy and ready. I dropped to my knees right there on the bathroom floor and took him in my mouth. The taste of him was salty and hot. I sucked him deep, gagging on that thick sons hard cock until spit ran down my chin. He grabbed my hair and fucked my throat, telling me how long he'd wanted this.
I pulled off, stood up, and bent over the sink. "Fuck me. Put that cock in your mother's cunt right now."
He didn't hesitate. He slammed into me in one thrust, stretching my pussy wide. We watched in the mirror as he pounded me, his balls slapping my ass, my tits swinging. "Harder," I begged. "Fuck me like you mean it."
He did. He railed me raw, one hand on my hip, the other reaching around to rub my clit. I came first, screaming, my cunt squeezing his sons hard cock until he followed, flooding me with thick ropes of cum. We didn't stop there.
I dragged him to my bed and rode him next, grinding down on that stiff shaft until I squirted all over his stomach. Then he flipped me onto my back, spread my legs, and ate me out before sliding back inside. We fucked for hours, switching positions, getting filthy. He came in my mouth, on my tits, and deep in my ass when I begged him to take it.
By morning we were still going, tangled in sheets soaked with sweat and cum. He looked at me with those hungry eyes and said, "This is just the start, Mom." I smiled and wrapped my hand around his sons hard cock again, already hard and ready for more.
